Two series of novel 4-phenoxypyridine derivatives containing imidazole-4-carboxamide and 4-methyl-5-oxo-4,5-dihydro-1,2,4-triazole-3-carboxamide moieties were synthesized and evaluated for their in vitro inhibitory activities against c-Met kinase and anti

A series of novel 4-phenoxyquinoline derivatives containing 1,2,4-triazolone moiety were synthesized and evaluated for their in?vitro cytotoxic activity against four cancer cell lines (HT-29, H460, A549 and MKN-45). Most of the compounds exhibited moderate-to-significant cytotoxicity. Compounds 33, 37, 39, 44, 46, 47, 53, 55, 61, 64 and 66 were further examined for their inhibitory activity against c-Met kinase. The most promising compound 47 (with c-Met IC50value of 1.57?nM) showed remarkable cytotoxicity against HT-29, H460, A549 and MKN-45?cell lines with IC50values of 0.08?μM, 0.14?μM, 0.11?μM and 0.031?μM, respectively, and thus it was 1.1- to 2.3- fold more potent than foretinib. Their preliminary structure-activity relationships (SARs) studies indicate that electron-withdrawing groups on the terminal phenyl rings are beneficial for improving the antitumor activity.
